How to get current logged In User information in ADF ?

How to obtain Logged In User information in ADF ?

Below are multiple ways how we can obtain the logged in User specific information in ADF
UI Layer
--------------------------
 #{securityContext.userName}

We can set default expression in view object attribute as below
----------------------------------------------------------------

adf.context.securityContext.getUserPrincipal().getName()
or
adf.context.securityContext.getUserName()

Java
-------------------
You can get User Name in Java code also using the following code.

     ADFContext adfCtx = ADFContext.getCurrent();
     SecurityContext secCntx = adfCtx.getSecurityContext();
     String user = secCntx.getUserPrincipal().getName();
     String _user = secCntx.getUserName();

How to access log files in Weblogic

How to access log files in Weblogic

Most of the times, In large scale environments, Weblogic application servers will be installed on linux machines. There are multiple ways we can access to log files to see application logging specific information or deployment log information.

One way is , Cd(Change directory) to corresponding log file folder in linux box and use linux commands to access the log files.

Another way is , connect to weblogic EM(Enterprise Manager) and follow below steps to see detailed log information.

- Connect to Weblogic Enterprise Manager
                 

-Expand Weblogic Doman, Right click on the corresponding cluster where your application has been deployed, Choose Logs , View Log Messages as shown below
                         

- Select the log file as shown below
                                       

- Click on Download button as shown below to copy to local folder.

How to build ADF UI components without using ADF Business Components

Usecase : How to build ADF UI components without using ADF Business Components

There is a way to build ADF UI components without using ADF Business components, For example if the application doesn't involve with any database transactions and all the UI components built on top of external data source, then we can eliminate use of business components and use simple POJO(Plain Old Java Objects) to build simple to Complex UI screens. Though we can use transient view object achieve similar functionality but requirement is totally eliminate use of business components (VO's , AM Impl) then below approach will workout very well

Implementation :

- Create a POJO with all the getter/setter properties for required attributes which need to be displayed on .jspx or .jsff

- Define a backing bean, Which holds the above defined POJO as a class level attributes with getter/setter properties.

- Drag the required UI components from the component pallet , and binds the each UI component value to backing bean. POJO properties.

- For eg : Define <af:table> component based on POJO , Remember we have to implement rangeSize, selectionListener,empListQueryListener operations

 <af:table value="#{pageFlowScope.EmpBean.empTable.tableRows}"
                          var="row"
                          rows="#{pageFlowScope.EmpBean.empTable.rangeSize}"
                          emptyText="#{pageFlowScope.EmpBean.empTable.emptyText}"
                          fetchSize="#{pageFlowScope.EmpBean.empTable.rangeSize}"
                          filterModel="#{pageFlowScope.EmpBean.empTable.filter}"
                          queryListener="#{pageFlowScope.EmpBean.empListQueryListener}"
                          varStatus="vs" partialTriggers="::refresh"
                          selectionListener="#{pageFlowScope.EmpBean.empTable.selectionListener}"
                          rowSelection="single" id="tEmp"
                          summary="Employee List" filterVisible="true"
                          selectedRowKeys="#{pageFlowScope.EmpBean.empTable.selectedRowKeys}">

- For eg : <af:inputText>

<af:inputText value="#{pageFlowScope.EmpBean.empPOJO.firstName}"
              readOnly="#{!pageFlowScope.EmpBean.displayReadOnly}"
              label="#{loadplanninguiBundle['COLUMN.FIRST_NAME_LABEL']}"
              id="it6">
</af:inputText>

-  With this approach, not required to create any data control as well.
